IMPROVEMENT IN LOCKS-AND KEYS.

Specification forming part of Letters Patent No. 178,669, dated June 13,1876; application filed March 21, 1876. v

To all whom it may concern:

Be it'known that I, JOHN JOSEPH PORTU- GUEZ, ot' the city, county, andState of New York, have invented a new and uset'ulImprovementin Locksand Keys, of which the following isa specification:

Figure 1 is a face view of -m y improved lock. Fig. 2 is a view of thesame with the face-plate removed. Fig 3 is a view of-the same with theintermediate plate removed. Fig. 4 is a cross section of the same, takenthrough the line as 00, Figs. 1 and3. Fig. 5 is an edge View of thesame, the case being shown in section. Fig. '6 is side view of the key,parts being broken away to showthe construction. Fig. 7 is a View of thekey, showing the bits in another position. Fig. 8 is .a yiew of the key,showing the bits in a third position. Fig. 9 is alongitudinal section ofthe key, taken through the line y 3 Fig. '6.

Similar letters of reference indicate corresponding parts.

The 'object of this invention is to furnish an imptoved lock for safes,doors, and other places where two parts are to be secured together, andwhich shall be so constructed that it cannot be opened by any otherinstrument than the key made expressly for it.

The invention consists in the combination of the pivoted bar providedwith an incline. and a notch, thepivoted bar provided with an arm, andthe sliding bar provided with a plate having guards anda'lockingpinattached to it, and their springs, with the intermediate plate of thecase for locking the pins attached to the bolt and its locking-bar, andfor cover- -ing the key-hole through said plate, and in the key formedof the two parts sliding upon and shutting into each other and the thirdpart, constructed and arranged to operate in connection with each other,as hereinafter fully described.

I will describe the mechanism of the lockin connection with themovements of the key by which it is operated, and'which I will firstdescribe.

The key is madein three parts, AB U. The inner part A is made with twoguards, a a and the lower end a of its stem projects in line with saidguards a a to serve as a pivot to the key. The part vB has three guards,b

axis of the key as the guard a of the part A. The guard b is upon theend of the part B.

- The upper guard b is made hollow to receive a pin,"as hereinafterdescribed, and the, lower sideot' the part B is grooved to receivev thepart A, as shown in'Fig. 6; The stem of the 7 part A is made long, andpasses through the hollow stem of the part B, which is made" shorter,through the hollowstem ot' the part 0, and its upper end is rigidlyattachedtothe upper end of the said part (3, so that the said parts A 0cannot turn upon each other. To

.the part 0 is attached the handle 0 which may be made in the form of aring, or in any other convenient form. The cavity of thepart O is madelarger than the stem of the part A, so that the hollow stem of the partB may be slippped up into the part 0, withdrawing the guards of the partB from the guards of the part -A, and allowing the parts A 0 to beturnedfwhile the part B. is held still. The upper part of-the stem ofthe part B has two slits formed in it, forming a tongue, b which issprungoutwarda little, so as to enter a recess in the inner surface ofthe part 0, and thus prevent thepart- B from slipping up upon the part Aaccidentally. This tongue is pushed in to allow the part B to be pushedup by a small pin, 0 passing in through the part0, as shown in Fig. 9.The stem of the part B has a collar or head, b formed upon it forconvenience in moving it up and down, and to limit its upward movement:

The case of the lock consists ofthe faceplate D, the intermediate plateE, the backplate F,'and the band G, which parts are bound togetherby't'our bolts, H. In the faceplate D is i'ormed the key-hole d. Thepart of the plate D through which the key-hole d is formed has acircular plate or cap, 6?, attached to it to give the stem of the key alonger bearing to keepitin position while being operated, without havingits lower end steadied by a pivot. To the lower side of the plate d atthe opposite sides of the forward end ofthe key-hole, are attached twopins, d which pass through the angle between the guards!) b of the key,and serve to prevent a key of any 'diate plate E. R is attached a plate,S, which has a short:

other shape frombeing inserted in the k'ey-. hole (1 and turned. As thekeypasses through the key-hole d it rests upon a plate, I, which isprovided with guards'i betweenwhich the guards of the key fit. The keyis'then turned a half-revolution to the right. As the key comes intoposition the guard I) strikes the incline jof the angularpivoted arm J,and pushes said arm back, Withdrawing .it from the pin 70 attached tothe bolt K, and which passes through a slot in the intermediate plate E,and from the pin ,i attached to the plate I. The guard b strikes thepivoted arm L and pushes it back, withdrawing its arm I from the pin mlattached to the: pivoted boa-r M, and which passes through a slot intheint'ermediate plate E. The'guard b strikes the projection 11/ formedupon or attached to the arm N and pushes it back. The arm Nis slottedlongitudinally, and slides upon two .pins or screws, and carries with itthe plate I. The arms J L N" are held forward by the three springs 0,attached to a block secured to the plate E. As the key completes itshalf-revolution it is pressed downward, which forces the. inner part Athrough the key-hole 6, formed inthe intermediate plate B. As the part Aof the key descends it enters a holein, the eccentric U, and the guard astrikes a pin attached to a plate, P, which rests upon and is held up bya spring,,Q, attached to the baclcplate F. To the plate P is alsoattached a rod, R, which passes up through a hole or socket formed inorattached to the-interme- To the upper endof the rod pin attached toits inner end to en ter the hole in the guard b of the part B of thekey, and

hold said partso that it will not be turned by Y turning the part A. Theguard at strikes: a

pinattached to a spring, T, Jandpushes it out of a hole inthe eccentricU, and thus unlocks the said eccentric. The parts A O of thekey are thenturned through an entire revolution, turning the eccentric U. As theeccentric U turns itstoe strikes the bar M, and pushes it. back,releasing the pin it attached to the bolt K. As the bar M moves back itpushes the spring-catch V out of its notch in the bolt K. I The toe ofthe eccentric U then strikes the ,11otch in said bar.

as herein shown and described.

The bolt K has two longitudinal slots formed in itto receive the screwsk to compel the; said bolt to always move in a straights line,

and which are screwed into the back-plate I f or into the bar or,b'locksattached to. said plate, and'upon which the said bolt K slides.The key is removed by drawing it upward, which raises the part A throughthe key-hole. in the intermediate plate E, and into the part B, and thenturning the keyahalf-revolution;

to the left. a

t a The lock is unlocked by turningthe key] a halt' rcvolution to theright, pushing the part A through the intermediateplate E,,l.l l(lfl1Illing it afull revolution to theleft. ,The key may i then be removedin thewmanner hereinbeforc 1 described.

Having thus described my invention, I claim as new and desire to secureby Letterslat- I ent- 1.
